The installation failed its [Date] inspección for [reason], and no follow-up inspección was scheduled. 5. UNDERPERFORMANCE: System monitoring shows actual production of [X] kWh over the past 12 months, [X]% below the guaranteed [X] kWh. The inverter error logs show [number] ground fault shutdowns. DAMAGES These defects have caused and continue to cause the following daños: - Interior water damage requiring drywall reparación: $[Amount] (estimate attached) - Mold inspección and potential remediación: $[Amount] (estimate attached) - Lost energy production value: $[Amount] (based on [X] kWh shortfall at $0.XX/kWh) - Independent inspección fees: $[Amount] - Risk of fire from electrical defects: incalculable but significant LEGAL CLAIMS Your company's failures constitute: - Breach of the installation contract and express warranties - Breach of the implied garantía of workmanship - Violación of [State] contratista licensing laws (License #[Number] was not properly qualified for electrical work) - Building and electrical code violacións - Negligencia causing property damage Under [State] law, willful contratista violacións may result in license suspension, bond claims, and enhanced daños. DEMANDAS Within fourteen (14) days of this letter, [Company Name] must: 1. Provide a detailed written remediación plan addressing all defects identified in the inspección report; 2. Schedule and complete reparaciones within thirty (30) days, to be verified by independent re-inspección at your expense; 3.

You are on notice that withholding payment for defectuoso work is lawful. Any attempt to file a mechanics lien for disputed amounts will be vigorously contested. Contacto me at [email/phone] to arrange inspección access and discuss resolution. Atentamente, [Abogado Name] [Firm Name] [Address] [Phone] [Email] Anexos: - Independent inspección report - Photograph documentation of defects - Production data showing shortfall - Reparación estimates - Building department permit records cc: [State] Contratistas State License Board [Contratista's Bonding Company]
If the installer is defunct, pursue claims against their contratista's bond (typically valid for 4 años after last renewal), file with the CSLB recuperación fund if available, pursue manufacturer garantía claims directly, and check if the installer had responsabilidad seguro that might still cover claims.
Sí, you can generally withhold payment proportional to the cost of correcting defects, but you must provide aviso por escrito of the defects and opportunity to cure. Document everything. The contratista may still file a lien, but your defecto claims provide a valid offset defense.
